Steps to reproduce

1. Clone repo: https://github.com/crip-home/vue-test-utils-issue
2. Run test: npm run test

What is expected?

Get defined component property

What is actually happening?

TS2339: Property 'prop1' does not exist on type 'Vue'.

---

If change in typings from:

export declare function mount<V extends Vue, Ctor extends VueClass<V> = VueClass<V>> (component: Ctor, options?: MountOptions<V>): Wrapper<V>

To:

export declare function mount<V extends Vue> (component: VueClass<V>, options?: MountOptions<V>): Wrapper<V>

Works as expected. I am new to typescript and I do not get why there is additional type in declaration.
